HP Modifiers

Below is a comprehensive list of everything in the game that directly affects your maximum HP.

Increasing your (buffed) Muscle also has an effect on your maximum HP, at a base ratio of one HP per Muscle point. This ratio is affected by the Percentage HP Increasers listed below, including the innate +50% for being a muscle class.

For these reasons, you may also be interested in the list of Muscle Modifiers. They are not listed alongside these items due to the variable nature of the Muscle-to-HP ratio. To see various maximum amounts of HP, see Maximizing Your HP.
